The wide supply range of 1.8V to 3.6V lets this MCU run directly from a single Li-ion cell or a regulated 3.3V rail, saving a regulator in cost-sensitive designs. ## Peripherals and connectivity — what's on the bus Connectivity interfaces cover I²C, IrDA, SPI, and UART/USART, so it can talk to common serial peripherals, infrared transceivers, or a host controller. ## Package and board mounting Housed in a 48-UFQFN Exposed Pad package (supplier device package 48-UFQFPN 7x7 mm), this is a surface-mount part. The tray shipping medium is fine for hand assembly or small reels; for volume reflow, order the tape-and-reel variant.","metaTitle":"STM8L151C6U6 8-bit MCU, 16 MHz, 32 KB Flash, -40 to 85°C","metaDescription":"STM8L151C6U6 8-bit MCU from STM8L EnergyLite series. 16 MHz core, 32 KB Flash, 2K RAM, 1K EEPROM, 41 I/O, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"16MHz","Series":"STM8L EnergyLite","Package":"Tray","RAM Size":"2K x 8","Core Size":"8-Bit","EEPROM Size":"1K x 8","Peripherals":"Brown-out Detect/Reset, DMA, IR, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"41","Core Processor":"STM8","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 25x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6627","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a6a751855e41d176288c66669f17dd61.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8L151C6U6/alternatives.json"},"ai":{"faq":[{"question":"What is the core size of STM8L151C6U6?","answer":"The STM8L151C6U6 has an 8-bit core processor, the STM8."},{"question":"How many I/O pins does STM8L151C6U6 have?","answer":"It provides 41 general-purpose I/O lines."},{"question":"What is the closest pin-compatible alternative to STM8L151C6U6?","answer":"Within the STM8L EnergyLite family, higher-density Flash variants (e.g., 64 KB or 128 KB) share the same 48-UFQFPN footprint and pinout, so a firmware-only migration is possible without a board spin.
